The relationship of gene polymorphisms of C-reactive protein with the development of myocardial infarction and formation of multifocal atherosclerosis in CHD patients
Abstract
Purpose. To assess the contribution of the CRP gene polymorphisms rs3093077, rs1130864 and rs1205 in the development of myocardial infarction (MI) and multivessel disease (MVD) in CAD patients based on gender and age. Material and methods. 303 patients with stable coronary artery disease were included in the study. C-reactive protein (CRP) levels were measured by high sensitive immunoturbidimetric assay. The genotyping studies were performed in 96-well plates using the TaqMan assay. Results. Male gender and older age are proven to be among independent clinical predictors of myocardial infarction and the development of MVD in patients with coronary artery disease. The rs1205 C/C CRP homozygous carriers have a significantly higher risk of multivessel coronary lesions at age > 65, regardless of gender (OR = 4.72, 95 % CI = 1.27–17.56; p = 0.045). The C/C genotype of rs3093077, A/G of rs1130864 and P/T of rs1205 in female patients reduce the risk of myocardial infarction (OR = 0.53, 95 % CI = 0.30–0.95; p = 0.0079, OR = 0.37, 95 % CI = 0.16 – 0.82; p = 0.0027 and OR = 0.35, 95 % CI = 0.14–0.84; p = 0.0097, respectively). The groups with and without myocardial infarction were comparable by the allele frequencies and genotype distribution combinations of the CRP polymorphisms (rs3093077, rs1130864 and rs1205). Regardless of a positive history of MVD and myocardial infarction, serum levels of CRP over 3 mg/L indicates a high risk of cardiovascular events in patients with stable coronary artery disease. However, there is no relationship between protein levels and the polymorphisms of the genes encoding them (p = 0.56). Conclusion: The prediction of myocardial infarction and MVD requires not only assessing clinical and demographic data of patients, but also measuring CRP levels and studying its gene polymorphisms.
